f7dd4f640a - rm the 'Memory allocation error' and 'Not enough memory' error messages from 
the compact and large model startup code, since they're not used (we rely on
  the DOS loader to check for the available memory instead)

dc17b55505 * switch to asmmode_i8086_intel instead of asmmode_i386_intel on i8086 when tp 
or delphi mode is selected. This fixes the error "Selected assembler reader
  not supported" in programs that specify $mode tp/delphi, but do not explicitly
  set $asmmode intel.

9b560ffd64 * x86 intel syntax inline asm: allow a segment override (segcs,segds,seges,etc.)

2f83e2efc9 * use 'seges' instead of db 26h. It is actually supported, but for some reason, 
unlike TP7's inline asm, in FPC it doesn't work on the same line as 'lodsb'.

d00c67f9d3 * limit the heap to 16kb in the i8086 far data memory models for the dos unit 
tests that execute a child process. Otherwise, by default, all DOS memory is
  reserved in these memory models, there's no DOS memory left for the child
  process and exec() fails.

a9ddf18779 + call SwapVectors before and after Exec under FPC as well. SwapVectors is 
implemented on two FPC platforms (go32v2 and msdos). On the platforms that
  don't need it, it does nothing, so it's safe to call on all platforms.

e367ccc0ee * MIPS: changed superregister number for $fcc0..$fcc7 to start from 32, so that range 0..31 can be used without translating into symbolic names. 
* Change register type of second operand in CTC1 and CFC1 instructions to R_SPECIALREGISTER, so it is not output using a symbolic name. Mantis #26380.

3164a10d9d * fixed a bug in the startup code for tiny memory model, which caused the 
program MCB address not to be calculated correctly, when the program is a tiny
  model .exe file, leading to possible memory corruption. Previously, the code
  assumed that dos_psp=CS, but that's only true for tiny .com files; tiny .exe
  files have a 256-byte gap between dos_psp and CS.
